One line for two products Offline robot programming While the BMW X3 was still in production, The company’s current achievements – Magna Steyr was awarded the contract to reflected by Magna Steyr Fahrzeugtechnik build the MINI Countryman®. Demanding Results AG & Co KG (Magna Steyr), its Austrian specifications required a stringent re-use Existing line almost subsidiary with main site in Graz – are the approach, with almost the entire bodyshell completely re-used low-volume production of the Aston manufacturing to be set up on the already Martin Rapide and the development and existing resources of the BMW X3. During Prototype costs saved manufacturing of the aluminum body for the ongoing production, the new product the Mercedes-Benz SLS AMG. A special needed to be planned in a way that the www.siemens.com/tecnomatix Results (continued) series production of the MINI Countryman Higher maturity of production could start on the same line without any line and robot programs on significant delays. This meant that all first tryout body-in-white processes of two very differ- ent vehicle types had to run almost parallel Shorter ramp-up time for a certain time. Required manufacturing capacity reached quicker Another challenging requirement was that Fewer process errors and less the prototypes should be built on this material waste single line. The aim was to save time and money by eliminating a separate prototype Increased in-house process Tecnomatix facilitates robot programming. production line and to achieve high com- knowledge patibility with the series production. “In view of these conditions, we had to review ronment, within an accuracy of +/- 5-10 our planning methods and processes,” says millimeters – significantly more precise Walter Gantner, strategy planner of than using conventional 2D methods. On Simulation/Manufacturing Planning at this basis, the four-man team (responsible Magna Steyr. “This task was only doable for bodyshell manufacturing of the BMW with virtual planning and simulation.” X3/MINI Countryman) planned the main line and the sub-line for the side frame. The result was a strategy change. Overall External service providers did the line project planning would now be executed building for the car’s front and top. almost completely using in-house resources; only portions would be “ The quality of the robot managed by external partners. In using programs determines the this approach, Magna Steyr aimed to quality of the line …With increase its own expertise, and to make Tecnomatix, we were able processes more efficient. To achieve this, to master the complexity.” Magna Steyr chose Tecnomatix® software from Siemens PLM Software. The choice Andreas Huber was based on experiences the company Bodyshell Planner had already gained on smaller projects Magna Steyr using Siemens’ digital factory solution.
